INDENTURE.

Application filed April 23,

This invention relates to indentures and while generally applicable tosheets of material, the parts of which are separable, as for example,check books, receipt books, order blanks, and similar articles Where asheet is to be detached so as to leave a record stub, it is primarilydesigned for use in package boxes, or other similar receptacles soconstructed as to provide a separable tongue adapted to be severed alongpredetermined lines so as to be removable or partially removable to makean aperture in the box and thus to gain access to the contents thereof.Heretofore in indentures of the nature to which the present inventionrelates, it has been customary to provide lines of perforations alongwhich the sheet is to be severed, as for example, in check books,receiptbooks, and the like. This is also for example, the custom in themanufacture of postage and been scored with roulette lines in someinstances. In all cases-of like nature as heretofore constructed and asI believe general experience has demonstrated, it is necessary to insuresevering the sheet on the desired line to first fold the same along theper forations forming a line on which the tear is to be made, andoftentimes even when this is done the sheet or the stub or sometimesboth, will be accidentally torn. The object of my present invention isto overcome this difliculty and at the same time to provide a manner ofscoring indentures which will not, I believe, weaken the sheet in whichthe scoring is made to' as great an extent as the perforations or othermethods common at the present time, tend at least, to so weaken thesheet. I have found that by scoring a sheet of suitable material withslits along predetermined lines and of a predetermined extent preferablyterminating at one extremity in the line along which the sheet is to besevered, the tear may be. made without first folding the sheet along theline in which it is desired to tear it and furthermore the sheet when soscored may be severed along the predetermined line without the liabilityof tearing the same or the stub or any remaining part of the sheetaccidentally along the lines on which it is not intended to be torn.Various manners in which this may be carried out will be hereinaftermore particularly described.

Inthe drawing: Fig. l'represents a check book provided other stampswhich also have figure in the 1918. .Serial No. 230,201.

with a series of scorings in a sheet which forms anindenture made inaccordance with this invention.

Fig.2 is a plan of a sheet provided with another form of scoring, Figs.3 and a are'views similar to Fig. 2 illustrating still other forms ofscoring.

Flg. 5 is a section on an enlarged scale showing a structure asillustrated in Fig. 4 in which the indenture is provided with slitswhich extend entirely through the material, and

Fig. 6 is a section on an enlarged scale showing the structure when thescore lines do not extend through the material of which the indenture ismade.

Referring to Fig. 1, 10 indicates a check book and is only illustrativeof one form of the application of the present invention. this figure,11, represents a blank check and '12 the stud attached thereto, thecheck and the stub forming an indenture'sheet which is to. be separatedalong the line indicated at a b. In this form of the invention I providea series of slits indicated at'13 and 14 arranged in' pairs a-ndat an.angle to one another, each pair of slits terminating at a point ontheline ab and forming an angle with erably atan angle to the line; a b.Furthermore, as is also apparent fromthe draw ing, the series of slits13on one side of the thereto and parallel to each line are oblique er.

other'side ofthe line a b, are also oblique thereto and parallel to eachother. In this form of the invention as will now be aopanx ent, thesheet may be separated alongthe line a b, by the usual method withoutthe'liability of i-lCCld-QllttlllY'tQill" ing either the "stub or thecheck along a. line on which it is not intended to be torn.

Referring to- Fig. 2, 15 indicates a blank sheet and 16 a stub fromwhich the sheet 15 is to be separated along the line '0 (Z. In thisinstance I provide merely a single line of slits 17 in predeterminedlength, preferably equal to each other and terminating at the right handextremity as viewed in this line c cl, along which the tear is to bemade; These slits are also preferably oblique .to the line 0 (Z andparallel to each other.

In Fig. 3 I have indicated a form of the invention somewhat similar tothat shown in Fig. 2. In this instance the sheet is incliwhile simllarlythe slots 14 on the in oftearing, and

each other, which also is prefcated at 18 and the stud at 19. The sheetis to be separated from the stub along a line 6 f and is provided with aseries of slits 20 which are similar in all respects to those in dicatedat- 17 in Fig. 2. In this form of the invention however, as indicated inFig. '3, along the line a 7 on which the tear is to be made, I mayprovite perforations 21 intermediate of the right hand ends of the slits20 and placed in the line along which the tear is to be made.

The same difference exists between the form of the invention shown inFig. 1 and that shown in Fig. 1', as exists between the form of theinvention shown in Fig. 3 and that shown in Fig. 2. In Fig. 1, the sheetof material is indicated at 22 and the stub from which it is to be tornat 23. A line along which the sheet is to be torn from the stub isindicated by g h. In this instance the slits 2 1 and 25 correspond tothe slits l3 and 14: in the form of the invention shown in Fig. 1, andalong the line of the tear g h intermediate of the points at which theslits meet I employ a series of perforations 26.

In the structure shown in Fig. 4 and as more clearly illustrated in Fig.5, the slits 2e and 25 are so made as to extend entirely. through thematerial of which the indenture is made. By reference to Fig. 6,however, it will be seen that instead of slitting the paper or othermaterial comprising the indenture the score lines may be indentations onone side thereof as indicated at 2 1, 25 in Fig. 6, and correspondingribs, for example, as indicated at 2& 25 in this figure of the drawingin which structure, as will'be understood the score lines pass onlypartway through the material of which the indenture is made.

As h reinbefore stated, while I have shown the invention as applied to acheck book, it is by no means limited to this use, as it may be employedin any instance where ordinary perforations are now employed to indicatea line along which parts of any material are to be separated, andfurthermore is particularly adapted to use in connection with paper orcardboard boxes in which various articles of food, for instance cereals,and breakfast foods, are now acked for the market in order to providetherein a tongue which may be separable along the lines of scoring togain access to the contents of the package.

In the ordinary form of perforating indenture sheets,.the perforating isdone by a separate independent operation, that is an operation which isseparately dependent from printing the sheet or otherwise preparing thesame for-use, whereas in scoring or slitting the indenture sheet inaccordance with my present invention the scoring or slitting may be donetogether with the print- 'ing operation by the mere addition of thenecessary scoring or slitting tool to the printing press. It willfurthermore be understood that the w-ords score and slit, as well asscoring and slitting, are synonymous as employed in this application,because in some instances it may be necessary and advisable to slit thematerial, whereas in other instances, merely scoring the same willanswer the same purpose.

I claim as my invention:

1. An indenture comprising a sheet of separable parts having betweenthema series of angular scores in pairs extending 0bliquely from a line onwhich the parts are separable, the said scores on corresponding sides ofthe line being parallel to each other and there being a perforationbetween the said pairs of scores in the line on which the parts of theindenture are separable.

2. An indenture comprising a sheet of separable parts having betweenthem a series of scores parallel to each other, terminating atcorresponding ends in a line on which the parts are to be divided, thesaid scores being also placed obliquely to the said line and parallel toeach other, there being a perforation placed between the ends of thescores on the line along which the parts are separable.

3. An indenture comprising a sheet ofseparable parts having between thema plurality of scores terminating at corresponding ends in a line onwhich the parts are to be separated, there also being a plurality ofperforations placed in the said line on which the'parts of the indentureare to be'sepav rated.

1. An indenture comprising a sheet of material having therein apluralityofimperforatepenniform scores to determine the line of separationbetween the parts of the sheet.

5. An indenture comprising a sheet of separable parts having arrangedbetween them a series of angular scores in pairs, with the scorespassing partially through the sheet and each pair of scores meeting onthe line on which the parts of the sheet are separable.

6. An indenture comprising a sheet of separable parts 'havingbetween,them angular scores passing only partially through the sheet andmeetingin a line on which the parts of the sheet are separable.

7. An indenture comprising a sheet of separable parts having a series ofangular score lines extending partially through the sheet and providingintermediate sections to determine the lineof separation of the parts,which line of separation of the parts is noncoincident with any of thesaid score lines.

8. An indenture comprising asheet of material having a pluralityofpenniform scores therein which extend 'only partially through thematerial of which'the sheet is formed.

Signed by me this 17th day of April, 1918.
